The aim of the study is to investigate the relationship of Juniperus Communis Lynn. with the bone mineral density in the rats fed with a high cholesterol (1%) diet. Thirty five Wistar albino rats weighed approximately 250-300 were used in this study. The rats are divided in five groups of seven each. Groups I and II were administered 0.5 ml of 0.5% Sodium Carboxy Methyl Cellulose (SCMC), while Groups II, IV and V administered 0.5 ml of juniperus communis linn dissolved in  25, 50, 100 mg/kg. Group I and Group II were fed with normal pellets while the other four groups were fed with pellets containing 1% cholesterol. Levels of lipid profile and High Density Lipoprotein Cholesterol (HDL-C) were defined in all the groups. Furthermore, bone mineral density (B M D) of the animals were obtained with DEXA scanner. BMD values of the rats did not show a different among the groups. Significant negative correlations were determined between BMD measurements and LDL-C levels in all groups connected with dose of Juniperus Communis oil. However, this relationship was not linear.
